Sudden movement of the machine or release of oil under pressure can cause injury to persons on or near the machine.To prevent possible injury, perform the procedure that follows before testing and adjusting the vibratory system.
Personal injury can result from hydraulic oil pressure and hot oil.Hydraulic oil pressure can remain in the hydraulic system after the engine has been stopped. Serious injury can be caused if this pressure is not released before any service is done on the hydraulic system.Make sure all of the attachments have been lowered, oil is cool before removing any components or lines. Remove the oil filler cap only when the engine is stopped, and the filler cap is cool enough to touch with your bare hand.
Care must be taken to ensure that fluids are contained during performance of inspection, maintenance, testing, adjusting and repair of the product. Be prepared to collect the fluid with suitable containers before opening any compartment or disassembling any component containing fluids.Refer to Special Publication, NENG2500, "Caterpillar Tools and Shop Products Guide" for tools and supplies suitable to collect and contain fluids on Caterpillar products.Dispose of all fluids according to local regulations and mandates.
To avoid damage to the vibratory system during testing, always perform the testing with the vibratory drum on top of tires or on loose dirt. Tires will simulate a non-compacted soil condition.Never operate the vibratory system when the machine is on concrete.
If a testing time longer than three (3) minutes is required, rotate the drum periodically in order to lubricate the eccentric weight shaft bearings.
Note: The hydraulic oil temperature should be at least 38°C (100°F).
Make sure that the parking brake is applied. Make sure that the propel control lever is in neutral. Make sure that the vibratory on/off control on the propel control lever is in the OFF position.

Right side of Drum (1) Vibratory motor. (2) Drain line.
Disconnect drain line (2) from vibratory motor (1) .
Install 4C-8689 Flow Meter between vibratory motor (1) and drain line (2) .
Install 4C-6500 Digital Thermometer into the hydraulic oil tank.
Move the vibratory amplitude control to the HIGH AMPLITUDE position.
Start the engine and run the machine at high idle until the hydraulic oil temperature reaches 38°C (100°F). Engine speed should be 2390 25 rpm.
Depress the vibratory on/off control to the ON position in order to start the vibratory system. The flow should be at a maximum of 3.78 L/min (1.0 US gpm).
Depress the vibratory on/off control to the OFF position in order to stop the vibration system. Stop the engine. If the flow rate is over 3.78 L/min (1.0 US gpm) the vibratory motor should be repaired or replaced.
Remove all test tooling and reconnect line (2) to motor (1) .
